light, portable, and etlective device for securing doors, and is intended especially for persons traveling to carry with them and fasten the doors of their rooms in hotels, Ste.

In order to enable others skilled in the art to which my invention appertains to make-and use the same, l will now proceed to describe its construction and operation, referring' to the annexed drawings, in whichl Figure l is a perspective view of my device. Fig. 2 is a cross-section, and Fig. 3 is a detail of one ofthe plates.

A and B represent two metal blades or The larger blade, A, has at its end two catches, a c, struck up from `the metal, with a vspace between them sufficiently large to admit a catch, b, struck up The larger blade, A, is made ot' thicker metal than the smaller one. The small blade, B, is to be used when the door ts very close, and the larger 011e when more loosely litting, and both combined when there is considerable space between the frame and door; and, further, when it is desired to geta still stronger hold on the door the small blade, B, is moved back and its catch I; passed through a slot, d, in the plate A.

It is a stud, passing through a slot, c, in the other en d of the small blade and through a hole in the larger blade, the slot e admitting of the smaller blade being moved out and in, as desired. On the stud h are placed two cogwheels, C C, one on each side ofthe two plates, and a screw, t', screwed into the end of the stud, as shown.

D represents a double or slotted wedge-key to straddle the blades, and provided with cogs x to engage with the wheels C C. This key is for the purpose ot'V gag-ing the diterent thicknesses of doors, and it has a tlange, m., on each side, which admits ofthe device being used on doors opening either way. In attaching this fastener the blades are put in the proper place,

and the closing of' the door drives the catches.

into the wood. The key D, being then placed over the blades "and pressed down and engaging with the cog-wheels, securely locks the door.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a door-tastener, the combination of the blade A, having catches a aand slot d, and the movable blade B, having catch b and slot c, as and for the purposes herein set forth.

2. In a door-.fastener having one or more blades with projecting catches, the combination ofthe cog-wheels C C and the doublecogged wedge-key D, for the purposes set forth.

3. The doublecogged wedge -key I), provided with sideanges, m m, in combination with the plates A B and cog-wheels C G, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence 0l' two witnesses.
